Integrate Orbeon Forms to OSGI

Hi everyone,

I'm trying to deploy orbeon.war (orbeon-4.4.0.201311042001-CE) to apache karaf (apache-karaf-2.3.3).
I deployed the war following the instructions described here.

Nevertheless I'm getting the following exceptions in the log file:

1. java.lang.NoClassDefFoundError: org/apache/log4j/Layout

For solving the [1] exception I tried the following suggestions but with no success:

Can anyone give me some hints on how to fix those issues? Has anyone else tried to integrate Orbeon with OSGI?

Thanks in advance

That sounds like an interesting thing to try, but we haven't tried this at all at Orbeon at least. Let us know if you make progress.
